Website profiling and frontend

Details

We built an energy management platform and we need to develop a frontend with profiling. We think that ruby is a good fit but we are open to other programming languages if they make sense. Integration with JavaScript is important since we want to use AMCHARTS JavaScript charting library. There are other modules we need to implement so, if the first module is implemented we will keep going with other assignments. A demo would be great. In attachment the details of the functionalities of the module.
